so after reading the other 200 page DIY thread about using an old computer fan, hard drive magnets, radio shack potentiometer and a random power supply I attempted to build my own. after many a failed attempts and finally getting a working combination using a 18V JBL power supply I found it was spinning to fast for my liking even on the slowest setting.
I saw another thread about this usb fan on amazon.com and said WTF might as well try it out. well let me tell you this works fantastic and is super easy to put together.

to my fan its an 80mm fan I didn't think I needed to spend the extra coin on the 120mm fan.
